Duna's KYB bet: Stripe alumni raise €40M+ for a reusable business identity network

Duna is an AI-native business identity platform founded in 2023 by two Stripe alumni: Duco van Lanschot, who ran Benelux and DACH at Stripe for three years, and David Schreiber, who spent six years there leading its largest global business unit, including the core card payments platform. Their bet was that corporate onboarding — know-your-business (KYB), KYC, customer due diligence and AML checks — was a decades-old manual cost center that could be rebuilt as a shareable, AI-verified network.

Instead of aggregating existing data sources the way incumbents Jumio and Veriff do, Duna generates its own verification data and targets what it calls 'patches of networks': tight clusters of companies that share customers — manufacturers with common buyers, investment firms with overlapping LPs, firms in the same small country — where reusing identity is valuable before full network effects arrive. The long-term vision is a 'digital passport for every business' enabling one-click onboarding across platforms, akin to Stripe Link for business identity.

Duna raised a €10.7M seed led by Index Ventures in May 2025, then a €30M Series A led by CapitalG in February 2026, with Index, Puzzle Ventures and Snowflake chairman Frank Slootman participating. Stripe CTO David Singleton, former Stripe COO Claire Hughes Johnson and Adyen CFO Ethan Tandowsky joined as angels. Customers include Plaid, CCV (Fiserv), Moss, Bol and SVEA bank, with reported 10.6x faster onboarding and 4.8x productivity gains.

TechCrunch called Duna the best-funded European member of the 'Stripe mafia', and the founders argue that compliance and identity consume up to 10-20% of a bank's total costs, making it an ideal target for AI automation. As of the February 2026 announcement the company remains privately held and scaling, with the network-effects payoff still ahead.
